Patented Nov. 21, 1939 UNITED STATES PATENT a is 2,180,410 ATTACHMENT FOR LINE CASTING Leonard G. Geissel, South Pasadena, Calif. Application February 2, 1939, Serial No. 254,172 I 11 Claims.

My invention relates to an attachment for typesetting machines such as Linotype, Intertype and the like.

An important object of the invention is to provide means to feed brass rule, leads, slugs, pre-set lines and other line-length elements used in the printing art, into the composing stick on such line casting machines.

Another object is to provide a key controlled means for feeding line-length elements into the composing stick of a line casting machine, between lines formed by the machine.

Still another object is to provide safety means which will automatically release an actuating lever in case the operation of the attachment is interfered with. I

The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear in the course of the following description.

' In the drawings, like reference characters designate similar parts in the several views.

Figure l is a broken front elevation showing an embodiment of my invention attached to adjacent parts of such a typesetting machine. a

Figure 2 is an enlarged bottom View looking in a the direction of the arrow A of Figure 1.

Figure 3 is a bottom view similar to Figure 2 but showing the parts in a different operative 0 position. a I

Figure 4 is an enlarged vertical section taken on the line 4-4 of Figure 1. v.

Figure 5 is a broken section taken on the line 5-5 of Figure 4.

Figure 6 is a section taken on the line 6-6 of Figure 2.

Figure '7 is a broken detail of means to remove elements from a magazine, as more fully described hereinafter.

The numeral 8 indicates a broken view of a vise frame of a Linotype, Intertype or the like. A locking bolt is shown at 9 provided with a handle I!) for tightening the vise frame in position opposite the molten metal pot (not shown).

Slidably mounted on the vise frame 8 is an elevator |2. Thus far is conventional construction.

Bolted to the elevator I2 is a cam l3.

The attachment includes a magazine It. for

rules, leads, slugs, or pre-set lines. A lug I5 is fastened upon the magazine M by means of legs 5 and I1. Bolt l8 fastens the lug and thereby the attachment in place at the side of the elevator l2. It will be noticed in Figure 2 that the 5 lug l5 has an inclined shoulder i9 along which the elevator l2 reciprocates. A bolted lug 2|), opposite the lug l5, similarly controls the opposite edge of the elevator l2.

Converging slides 2i and 22 together form a chute that receives line-length elements from the 5" magazine M and directs such elements into the composing stick (not shown) of the machine;

An arm 23 on the lug i5 provides a shaft 29 upon which a lever 2t oscillates. The lever 24 comprises arms 25 and 26. lever 24 provides means for the oscillation of such lever. The arm 25 of the lever is disposed in the path of the cam l3.

, An auxiliary arm 28 is also mounted to swing on the shaft 29. Movement of the arm Wis 15 communicated to the arm 23. by means of a rela: tively stifi spring 39 which has legs 3| and 32 that are bent around both the arms 26 and 28. This spring tends to cause the arms to follow each others movements unless the arm 28 20 strikes a substantially immovable obstruction, in either direction. In such event, the arm 26 may swing relative to the arm 28.

Another spring 33 is also mounted on the shaft 29. This latter spring; has one end fas- 25 tened to a collarfid on the arm 23 and the other end 35 of the spring 33is hooked around the arm 25. By this arrangement the spring 33 tends to return the lever 2t to the position shown in Figure 2. I

A reciprocating selector 35 reciprocates in oppositely grooved slides 31. The selector 36 has a notched face as best shown at 38 in Figure '7. This notched face 38 receives the printing edge of the rule 39 or other line-length element in the 35 magazine M. I

A coil spring Ml on a pin M adjustably supports the selector 36 with regard to' the bottom 'of the magazine M. The selector plate 36 is hooked through a reciprocating bar 42, upon which bar the spring ll and pin M are mounted by means of a yoke 43. A plate M on'the yoke 43 is apertured, as shown at 45, for receiving a reduced end 46 of the arm 28. A stop 4! limits movement of the plate M to the right in Figure 6. 45 The spring 33 tends to move the plate 44g through the intermediary of the arm portion 46, against the stop 41.

Mounted at either side above the slides 21! and 22 is a pair of rods 48. Slidable on these rods 50 between stops 49 and 553 is a flanged plate 5|, one of whose flanges 52 is opposite a relatively stationary flange 53 above the slides 2|, 22. A helical spring 54 tends to move the plate 5| to a position in which a rule, lead, slug or pre-set 55" A bearing-2'! on the 10.

line 39 is supported on the flanges 52, 53 above the slides 2|, 22.

To withdraw the plate 5| and its flange 52, a lever 55 is provided with a key 56 readily accessible to the operator. The lever 55 is fulcrumed at 51 on a lug 58 on the magazine. One end of a bar 59 is pivoted at 60 on the lever 55. The other end of the bar 59 is fastened to an ear 6| on the plate 5|.

A hook 62 on the plate 5| face 63 which is engaged by a pin 64 on the bar 42. When the pin 64 has caught under the hook 62, as shown in Figure 3, the reciprocating bar 42 is held in the position shown in the latter figure until the operator releases the plate 5| by means of tapping the key 56. Tapping the key 56 not only releases the reciprocating bar 42 so that spring 33 may return to its original position, but also withdraws the flange 52 allowing the element to drop down the chute provided by the slides 2|, 22.

In the operation of my present device, a supply of rules, leads, slugs or other line-length element are inserted into the magazine l4 and rest on the top of the grooved slides 31.

When the elevator |2 descends, the cam l3 engages the lever arm 25 thus tripping the lever 24. Movement of the lever arm 26 carries with it the arm 28, which in turn reciprocates the selector 36, which pushes the bottom element from the stack in the magazine over until said element rests on the flanges 52 and 53 above the slide elements 2|, 22. As soon as the selector has moved the bottom element over on the flanges 52, 53, the pin 64 on the reciprocating bar 42 is caught under the hook 62. This maintains the lever 24 in a tripped position until the element that is resting on the flanges: 52, 53 is released. This combination of elements prevents the cam l3 from tripping the lever 24, as long as there is an element on the flanges 52, 53.

When the operator Wishes one of the elements to be fed from the present attachment, he depresses the key 56, which moves the plate 5| to the left in Figure 5, thus drawing the flange 52 out from under the element 39, which causes the element 39 to drop down the chute and into the composing stick. As soon as the plate 5| withdraws its associated hook 62, the spring 33 moves the lever 24 back to the position shown in Figure 2, so that it is ready to be tripped upon the next descent of the elevator |2.

While I have illustrated and described what I now regard as the preferred embodiment of my invention, the construction is, of course, subject to modifications withoutdeparting from the spiritand scope of my invention.
